Artemisia lerchiana Based Green Synthesis of Silver Nanoparticles: TEM Microscopy, Physicochemical, and Spectroscopic Characterization.

Silver nanoparticles (AgNPs) have unique physicochemical characteristics that render them very appropriate for various biomedical applications. AgNPs were synthesized in a study by an environmentally friendly and cost-effective method where an aqueous extract of Artemisia lerchiana was used as a bioreducing and stabilizing agent. To characterize the synthesized nanoparticles, a conjunction of analytical methods was employed, such as UV-Visible spectrophotometry, Fourier Transform Infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and atomic force microscopy (AFM). The UV-Vis spectrum indicated the formation of nanoparticles with a typical surface plasmon resonance peak situated at 480 nm. TEM examination showed mostly spherical-shaped nanoparticles with a size of 4-19 nm. FTIR spectra showed the presence of functional biomolecules that reduced silver ions and gave AgNPs stability. This green synthesis method highlights the possibility of using plant-based nanoparticle synthesis in biomedical, environmental, and industrial fields.
